Pneumatic Wafer Butterfly Valve

Heyue high-performance Pneumatic Wafer Butterfly Valve - the ultimate solution for efficient flow control in diverse industrial applications. Engineered with precision and reliability, this center-line designed valve combines compact construction with exceptional sealing performance, making it ideal for space-constrained installations and demanding process conditions.

Compact Wafer Design: Lightweight construction with through-bolt installation reduces space requirements and simplifies maintenance while ensuring leak-tight performance

The water and wastewater treatment industry is one of its core application scenarios:

Urban water supply/drainage networks: Used for flow regulation at water plant inlets and clear water tanks, and for opening and closing transmission pipelines in urban sewage networks;

Wastewater treatment plants: wafer butterfly valves suitable for controlling the flow of media in sedimentation tanks, filtration systems, and aeration tanks. The compact wafer-type structure is suitable for installation in crowded machine rooms/pipelines, and pneumatic drive allows for automated start and stop via the central control system.

 

HVAC (Heating, Ventilation, and Air Conditioning) and Building Automation

Central air conditioning systems: Control the flow rate of cooling water, chilled water, and hot water, automatically adjusting the flow rate in conjunction with the temperature control system to maintain a constant indoor temperature by the pneumatic wafer butterfly valves.

Large machine room ventilation ducts: In some ventilation systems (with airflow regulation requirements), wafer butterfly valve with pneumatic actuator used to control the on/off and airflow regulation of fresh air/return air.

 

Food and Beverage Industry (Sanitary Grade)

When paired with a 316L stainless steel valve body + food-grade seals (such as EPDM/PTFE), the pneumatic wafer butterfly valve with sanitary type can be used for:

Liquid raw material transportation: Opening and closing of pipelines for fruit juice, dairy products, and drinking water;

Filling/packaging stages: Flow control of materials in the production line. Pneumatic drive avoids manual contact and contamination, and the wafer-type structure facilitates quick disassembly and cleaning (suitable for CIP/SIP sterilization processes).

 

Chemical and Petrochemical Industries

Material transportation pipelines in chemical plants: wafer butterfly valve used for on/off and flow regulation of intermediate products. Pneumatic drive supports remote control, avoiding personnel contact with hazardous media;

Petroleum storage systems: Opening and closing of pipelines for finished oil products (such as diesel and gasoline) in tank farms. The wafer-type structure saves space in the tank farm pipeline layout.

 

Power Industry

Used in auxiliary fluid systems of power plants and substations:

Cooling circulation systems: Control the flow rate of cooling water for turbines and generators. Fast pneumatic opening and closing can adapt to changes in unit load;

Desulfurization and denitrification systems: On/off control of process water and absorbent solution pipelines in the flue gas treatment stage. Pharmaceutical Industry (Sanitary Grade)

Suitable for sterile production environments:

Drug solution transfer and dispensing systems: Used for pipeline transfer of injectable and oral liquid medications, pneumatic automation control avoids contamination risks associated with manual operation;

Clean area fluid pipelines: Clamp-type structure for easy disassembly and sterilization, and the use of sanitary-grade seals meets GMP (Good Manufacturing Practice) requirements.

 

Municipal Engineering and Light Industry

Urban gas distribution: On/off control of some low-pressure gas pipelines (requires compatible gas-specific seals);

Dyeing/Textile industry: On/off control of dye solutions and rinsing water pipelines, wafer butterfly valve with pneumatic drive can be linked to the production line for batch control.
